Do I really need a timing cover gasket set - Help! on 1999 Mercury Sable

Car running fine - just didn't have heat from time to time. Had to add water in radiator - car never overheated and also did not go to red on temp guage. I don't see any leaks but am monitoring everything now - could I just monitor all fluids and run car without replacing the timing cover gasket set? Parts are nothing but labor is outrageous making cost almost $600.
